 210, "Regulations Governing the Interstate Movement of Live 

 Stock," dated May 20, 1914, and effective July 1, 1914, as 

 amended, be, and the same are hereby, further amended so 

 as to permit the use of "saponified cresol solution" as a sub- 

 stitute for compound solution of cresol U. S. P. in the disin- 

 fection of cars, boats, other vehicles, and premises that have 

 contained live stock affected with a contagious or communi- 

 cable disease, for the disinfection of swine to prevent the 

 spread of hog cholera and swine plague, and for preparing 

 a dressing for sheep to prevent the spread of lip-and-leg 

 ulceration (necrobacillosis) ; provided, however, that such 

 saponified cresol solution shall conform to the following re- 

 quirement: 



1. The formula of the product shall employ not less than 

 28 per cent by weight of linseed oil. Either caustic potash, 

 caustic soda, or a mixture of caustic potash and caustic soda 

 may be used to saponify the linseed oil. The cresol used 

 must be at least 95 per cent pure, and enough of this com- 

 mercial grade of cresol (cresylic acid) must be employed in 

 compounding the disinfectant to bring the actual amount of 

 cresol in the finished product up to 50 per cent. 



2. The product shall remain a homogeneous liquid when 

 cooled to 32 F. It shall contain substantially no unsaponified 

 linseed oil or excess alkali. It shall be readily soluble in 

 cold distilled water; the solution shall be practically clear 

 and shall contain no globules of undissolved oil or cresylic 

 acid. 



3. Manufacturers wishing to offer saponified cresol solution 

 as indicated above for use in official disinfection must first 

 submit a sample of at least 8 ounces for examination, together 

 with a statement of the formula employed and a guaranty that 

 the product will be maintained of a quality uniform with the 

 sample submitted. 



4. To prevent confusion, each product must bear a dis- 

 tinctive trade name or brand, together with the name of the 

 manufacturer or distributor. 1 There shall be no mention of 

 the United States Department of Agriculture or the Bureau 

 of Animal Industry on the labels, containers, or printed 

 matter accompanying products permitted to be used in offi- 



iA "Rule to prevent the spread of scabies in sheep" is in ef- 

 fect through the entire year. This rule prescribes the quar- 

 antined area in the respective States and should be considered

 be obtained from the Chief of the Bureau of Animal Industry,
